Characteristics of plates
One of the main parts of a plate heat exchanger of any type (folding or soldering) are plates. The heat exchanger plate is a stamped steel sheet with a thickness of 0.4 to 1.1 mm. The height and width of the plate depend on the heat exchanger size, which is selected depending on the power of the heat exchange and temperature loads.
The main characteristic of the heat exchanger plate is heat transfer coefficients (vary from 750 to 8200 W /(m 2 * 0 c) depending on the type of plate and mode The operation of the heat exchanger) and the pressure loss of the working medium during the passage of the channel formed by two adjacent plates (pressure loss varies from 0.02 to 0.8 bar, depending on the type of working medium.
To improve heat transfer plates of the heat exchanger during a stamping from a flat metal sheet, a bulk corrugated shape is given, as a result of which the plate area increases, and when two corrugated plates are connected, the heat exchanger canal with a much larger heat transfer coefficient compared to a flat sheet metal.
The most common plate thickness is 0.5 mm thick. In broad-channel heat exchangers, plates are applied to 0.9-1.1 mm thickness. The plates with a thickness of up to 0.6 mm are assembled in such a way that the point contact is provided between adjacent plates in the package of the heat exchanger plates. When applying plates from 0.8 to 1.1 mm is provided without contact assembly of the channels of the plates (the point contact between the plates is missing), as a result of which it becomes possible to pass between the channels of the collapsible plate heat exchanger of viscous media and environments with inclusions
Plates of the same size as a rule have several so-called profiles. Profile is a view of a corrugated pattern on the plate. The heat exchanger plates profiles may be rigid (such as h = high ), medium ( m = mix ) and Soft ( L = Low ). The selection of the type used in the heat exchanger plate is determined when calculating the heat exchanger to the specified parameters. So, under the condition of minimal pressure losses, L-profile plates are used, providing the passage of heat exchanger channels with minimally possible pressure losses. At the same time, if necessary, the calculation of the minimum size heat exchanger with the minimum possible area of heat exchange is used by the H-profile plates providing the highest heat transfer coefficients, but at the same time the highest pressure losses in the heat exchanger.
